hands-on with Kubernetes

https://kubernetes.io/blog/2019/07/23/get-started-with-kubernetes-using-python/

• A Kubernetes service - I’m using Docker Desktop with Kubernetes in this walkthrough, but you can use one of the others. See Getting Started for a full listing.
• Python 3.7 installed
• Git installed

FROM python:3.7

RUN mkdir /app
WORKDIR /app
ADD . /app/
RUN pip install -r requirements.txt

EXPOSE 5000
CMD ["python", "/app/main.py"]

1. Get the official Python Base Image for version 3.7 from Docker Hub.
2. In the image, create a directory named app.
3. Set the working directory to that new app directory.
4. Copy the local directory’s contents to that new folder into the image.
5. Run the pip installer (just like we did earlier) to pull the requirements into the image.
6. Inform Docker the container listens on port 5000.
7. Configure the starting command to use when the container starts.

docker build -f Dockerfile -t hello-python:latest .

docker run -p 5001:5000 hello-python

Running in Kubernetes

install kubernetes,


brew install kubectl
